An increasing weight of evidence implicates early inflammatory events as inhibitors of functional recovery in both peripheral and central neuropathologies. In this study, we investigated the role of the inflammatory TNF-α/NF-κB axis on events subsequent to sciatic nerve crush injury in rats. Electrophoretic mobility shift assays (EMSA) revealed that within 6 hours post-crush NF-κB DNA binding a...

Polyacrylamide gel genome electropherotyping and negative-stain electron microscopic studies, along with immunofluorescent staining and immune electron microscopy reactions, indicate that rabbit syncytium virus has the morphologic, genomic, and antigenic attributes of a Kemerovo serogroup orbivirus.

The preparation of the first monoclonal antibody (MAb) against the orthomyxovirus-like infectious salmon anaemia (ISA) virus is described. Characterization of the MAb included isotyping, enzyme-linked immunosorbent assay (ELISA), immunofluorescent staining of virus infected cell cultures (SHK-1 cells), immunoelectron microscopy (IEM) of negatively stained virus preparations, virus neutralizatio...

background: the purpose of this study was to create biomaterial scaffolds like platelet-rich plasma (prp) and platelet-rich fibrin (prf) containing stromal cell-derived factor-1 (sdf1) as a chemokine to induce hyaline cartilage regeneration of rabbit knee in a full thickness defect. methods: we created a full thickness defect in the trochlear groove of thirty-six bilateral knees of eighteen mat...

In previous work we transferred a human factor IX-encoding adeno-associated viral vector (AAV) into skeletal muscle of men with severe hemophilia B. Biopsy of injected muscle up to 1 year after vector injection showed evidence of gene transfer by Southern blot and of protein expression by IHC and immunofluorescent staining. Although the procedure appeared safe, circulating F.IX levels remained ...

Vascular smooth muscle cells (VSMC) in the rat mesenteric artery show specific immunofluorescent staining with antisera against purified human uterine myosin (ASMM) but not human platelet myosin (APM). However, in primary cultures produced by enzymatic dissociation of this vessel, VSMC stain specifically with both ASMM and APM within 5 h after plating and throughout growth to confluence (4-10 d...

Immunopathological investigations of the small round cells infiltrating into the tissues of human renal allografts and also those in urinary sediments were performed, using anti-human T-lymphocyte serum (AHTS). AHTS made from ALS is highly specific for T cells, but not for B cells. Tissues obtained by needle biopsy were examined by immunofluorescent staining and conventional histopathological m...
